And now for the first time, scientists have discovered how they do it.http://phys.org/news/2015-07-bees-naturally-vaccinate-babies.html

A team from the University of Alaska Fairbanks and the USDA have now completed a two-year study on bumble bees in agricultural areas in the region. The research was published in the Biodiversity Data Journal.http://phys.org/news/2015-06-bumble-bees-frontier.html

Plants & Animals Wed, 20 Aug 2014 07:40:01 EDTnews327734586Fipronil and imidacloprid reduce honeybee mitochondrial activityNew research published in Environmental Toxicology and Chemistry addresses the effects of two broad-spectrum systemic insecticides, fipornil and imidacloprid, on honeybees. These insecticides are widely used in agriculture, and the authors conclude that fipronil and imidacloprid are inhibitors of mitochondrial bioenergetics, resulting in depleted cell energy. This action can explain the toxicity of these compounds for honeybees.http://phys.org/news/2014-08-fipronil-imidacloprid-honeybee-mitochondrial.html

This practice has come under scrutiny, however, in response to colony collapse disorder, the massive—and as yet not fully explained—annual die-off of honey bees in the U.S. and Europe. Some suspect that inadequate nutrition plays a role in honey bee declines.http://phys.org/news/2014-07-scientists-track-gene-honey-bees.html
